l 'My invention relates to safety razors .and

is particularly applicable to the class of safe- Aty razorsAcomprisirlig a guard, a backing and a thin flexible bl e c amped betweenthe 5 guard and the backing to retain the cutting edge of the-blade inshaving relation to the guard teeth, In the clam of razors describedA ithasbeen customary, so far as I am aware,

to provide the backing member I0 that project through holes in theblade'and into holes in the guard member, Wherebyi n DI'IeSPOndlng parts1n the several views.

the blade and the backing are retained from'- rotation on the guard bythe cooperation of.v

said pins with the guard andthe clamping 15 of the blade between theguard member and the backin member, sothat the blade-per# forms nonotion in retaining any ofsa'id .parts with relation one toanother.

. The object of" my invention '1s to provide a safety razor whereinjwith a guard membeiwto-retam theA blade 1n shaving relation. thereto andthe blade, will also cooperate with abackin member to retain the latterin proper relation to the blade for shaving purposes, so that-:theposition of the backin member with regardA to the guard mem er-ismaintained by the blade and not by `the cooperation of said memberstogether in the ,well -known manner I have .30 described above. y-

In carrying outmy invention I provide a guard member and a blade havingcooperative means to retain the 'blade in shaving position n the guard,a backing member for the blade, means cooperative between the blade andthe backing member whereby the blade retainsthe backing memberinoperative relation to the blade vand the guard, and means to causetheguard memberandbaek- '.40 ing member to clamp the blade therebetween.

Similar numerals of reference indicate The guard member is indicated at1, vthe blade `is indicated at 2, and at 8 is a backing member, soorganized that the blade may be clamped between said members` The uardmember is shown of the varietyhavard teeth I? on 'opposite sides-alongvAny suitable means may be rovidedfor causing the blade to be clampebetween the guard `member and the backin `member. In the, exampleillustrated the ackin'g member 3ds provided with'a threaded projectionl4 adapted topass through a centrally disposed hole inthe guard membertoA receive the internalportion of a suitable handle t5 to clampl theparts together for shavin The blade is provided with a substantialycentrally disposed opening 2a vthrough which the projection 4 of thebackingmember may pass when the blade is between the members 1 and 3.lIJIeretofore, so far as I am aware, the opening in the blade for the,projection from the backing for clamping the parts together has beencircular so that `reliance was had `upon spacedy pins projectxin fromthe backing to pass through spaced ho es -in the blade and i to holes'in the guardmember to keep the b ade and backing in osition on theguard member. In accor ance with my invention I provide co-` operativemeans -bet-weenfthe blade'and the guard member to keep the blade fromrotat- Fig. 5 is a longitudinal section on line in'g'o'n said member.For such purpose IQ -provide a projection 1b on-the blade side of tionto the blade and the guard snugly to receive the metal""at thesidesbfAopening 2a so that the blade will, by sald means -to receive theprojection `1b of the guard member, for which purpose I have shown thebacking member provided lwith an outwardly disposed depressed orrecessed portion 3a which will receive the projection 1b while the sideportions of the backing member bear upon the blade for clamping itagainst the gua-rdf member.

When the parts are to be assembled for use;l the blade may be placedupon the guard member so that the projection 1b of the latter will enterthe opening 2 of the blade and thereby the blade is positioned in properrelation to the guard, and the backing member 3 will be applied upon theblade so that its projection 4 will pass through the4 blade and theguardmember and the projectionsl 6 willenter the openings or recesses 2bof l the blade, whereby the backing, by means' of the blade, is properlypositioned upon theblade with respect' to its cutting edges and withrespect to the guard teeth, whereupon the handle 5 will be screwed uponthe projection 4, thefhandle engaging the guard member, Vto clamp theparts firmly together for shaving, (Fig. 5v). The projections or pins 6do not cooperate with the guard b member to retain the backing member 3with respect to the guard member, the guard member being shown shorter,where the projections 6 extend throughthe blade, than the distancebetween said projections in the direction of the length of the guardmember, so that the latter does not interfere with the projections 6.The guard member 1 and backing member, 3'are shown curved 1n atransversedirection whereby a thin blade 2 may be clamped. therebetween in acurved shape to stifl'en the blade ina well known manner, although theguard member and backing member may have other shape if desired.

In accordance with my invention the blade is retained upon the guardmember in the pro er position by means of the cooperation of t eprojection 1b and the sides of opening 2a of the blade irrespective ofthe backing, sothat when the blade is placed upon the guard member saidparts will be in Vof the projection,

proper ositipn to receive the projection 4 backing* without theinconvenience sometimes experienced ofhaving to manipu' late the bladeto register its holes with spaced holesfof -the guard, as heretoforeknown, and when the backing is applied upon the blade it will immediatelbe posi- .tioned and retained by reason of t e projections 5 enteringthe openings or recesses 2b in the blade, so that the parts areconveniently yretained to receive the handle for clamping the partstogether, the blade performlng a new function in retaining the backingmember'A with relation to the blade and to the teeth of the guardmember.

Having now described my invention what Iclaim is:

1. A blade having 'a non-circular opening substantially centrallydisposed to retain the blade in shaving relation to a guard member, saidblade having means spaced from said opening to cooperate with a clampingmember to retain the latter in shaving relation to the blade independentof the guard member.

2. Al blade having an angularly shaped -opening disposed substantiallycentrally in the blade'to. cooperate with a guard member to retain ytheblade in shaving position thereon, and said blade being provided withmeans spaced from said opening to cooperate with a backing member toretain `the latter in vshaving relation to the blade and to the guardmember.

3. A safety razor comprising blade clamping members, a blade, meanscooperative between one of 'said members and said blade to retain thelatter in shaving relation tosaid member, said blade and the othermember having cooperative means whereby the blade will retain saidmember in an operative position respecting the blade, and means todetachably clamp the blade between said memers. f

4. A safety razor comprising blade clamping members, a blade adapted tolit between said members, and means to clam said members upon saidblade, one of sai members having means cooperative with the blade toretain the blade in operative relation to said member and the othermember having means cooperative with the blade independent of the firstnamed means whereby thekblade will retain said member inoperative-relation to the blade independent of the irst named means.

5. A ,safety razor comprising a guard member having a projection on oneslde, a blade to lit upon said side of said member, said blade having anopening to receive said said projection and the opening of the bladebeing cooperative to retain the blade from rotation on said member, abacking member for the blade, and means to clamp said blade betweensaidnmembers, said blade and backing member ;having cooperative meansindependentof the kguard. member wherebyl the'blade will retain thehacking member in shaving relation to the blade.
